Error on WLS Patching in EBS R122 - Patch was not found in the patch catalog

Today I have faced an issue with WLS patching and observed the MT ETCC utility has listed the patches missing from the WLS home. However some of those patches are already applied and those installed patches also listed in MT ETCC report as not applied. So I have checked whether patches are properly applied or not with using following command - "bsu.sh -report | grep -i XXXX"  and observed below error message.

$ bsu.sh -report | grep -i XXXX

ERROR..................... Patch "XXXX" was not found in the patch catalog. Make sure your catalog is up to date.
WARNING................... Archive for Patch "XXXX" is not availabe, details skipped. Download the archive to generate the full report.
Patch ID.................. XXXX  
$

Then I tried to remove that WLS patch, but got error as "Encountered unrecognized patch ID"

$ sh bsu.sh -remove -patchlist=XXXX  -prod_dir=$MW_HOME/wlserver_10.3 -verbose

Encountered unrecognized patch ID: XXXX       

Again try to install that patch, now this time noticed that "Patch already installed:XXXX in profile: Default"

$ sh bsu.sh -install -patchlist=XXXX -prod_dir=$MW_HOME/wlserver_10.3 -patch_download_dir=$MW_HOME/utils/bsu/cache_dir -verbose

Patch already installed: XXXX in profile: Default  

Using below command, I have confirmed that WLS patch catalog was corrupt or missing for file system "fs1". That's why the MT ETCC is listing all patches as missing for WLS as no patch data is recorded for this home.   DownloadDir (/u01/HYDINFRA/working/WLSPathces) was used non-default directory for patching and that directory (/u01/HYDINFRA/working/WLSPathces) also does not exist.

$ cd $FMW_HOME/utils/bsu

Workaround for this issue:

1) Created same directory structure and copied all missing patch information.

$ mkdir -p /u01/HYDINFRA/working/WLSPathces 

$ cp -r /u01/HYDINFRA/R122EBS/fs1/FMW_Home/utils/bsu/cache_dir/*  /u01/HYDINFRA/working/WLSPathces

2) Re-tested BSU report and confirmed that no errors now.

$ bsu.sh -report | grep -i XXXX
      Patch ID.................. XXXX

3) Re-ran MT ETCC checker and noticed correct results returned.

To overcome this issue permanently, you need to ensure the next patch will be applied on the correct/default patch_download_dir.

$ cd $FMW_HOME/utils/bsu

$ bsu.sh -install -verbose -patchlist=XXXX  -prod_dir=$FMW_HOME/wlserver_10.3 -patch_download_dir=$FMW_HOME/utils/bsu/cache_dir 

Thats it. Hope this article will help you.
